I have to wonder what Amazon was thinking, building such a labor-intensive operation four hours from the nearest major labor pool.
Distribution centers are often located way out in the middle of nowhere because that's where the cheapest land is. They don't need to be near a major population center unless they are looking to staff the place with skilled labor, which they aren't. After all, the Coffeyville area certainly does seem to have enough of a population base to support Amazon's operations most of the year.
Many people are unenthusiastic about their work.
